Fidelity

By: IsoldeLovesTristan



"Okay, I'll be back in about half an hour."

"Awesome...hey, get some more ice while you're out."

"Yeah, right, as if there'll be any left." Ryan closed the door to the apartment behind him.

Lana stood up and crossed the room to adjust one of the large fans that sat beneath the window. Satisfied with the new angle, she flopped back onto the couch, opposite Jack, her boyfriend's roommate. "Shit, it's hot in here," she complained. 

Jack leaned forward to grab the TV remote off the coffee table and hit the power button, turning the television off. "Hey, what'd you do that for?" Lana asked.

Jack didn't answer, but the look on his face said everything. Lana caught his gaze and laughed, rolling her eyes. "Oh no, not this again."

"Come on, you can't tell me that..."

"Jack, we've had this discussion before. Many times. Nothing's going to happen."

"But you just sent Ryan out to get more beer."

"Because we needed more beer."

"You could have gone with him."

"And go back outside into that humidity? I think not."

"You have an answer for everything, don't you."

"You know I do," she said, giving him a sly smile.

Jack sighed and leaned back into his corner of the couch. It was just his luck that the sexiest, smartest, most charming girl he knew would come into his life in the form of his roommate's girlfriend. At first, he had figured that he would just leave the two of them alone and just be civil to Lana whenever she came over, but she had insisted on getting to know him so that she could be sure that "her boy was being taken care of properly". Jack hated to admit it, but part of him had hoped that someone that gorgeous would be something of a bitch so he could find a reason to dislike her. Alas, his plans had backfired. 

He turned back to look at her. She had reclined against one of the large pillows in the corner of the couch, head back and eyes closed. Her long, dark blonde hair was piled in a sloppy ponytail on top of her head, the little wisps around her forehead moving slightly in the breeze from the fan. Her cheeks were pink from the heat and there was a thin layer of sweat covering her face. Jack watched intently as a droplet slid down her neck and into the collar of her sleeveless blouse, the buttons of which were straining against the weight of her large breasts. He let out the smallest of groans as he felt the familiar stirring in his shorts. 

Despite his attempts to mask it, the noise caused Lana to open her eyes. Realizing that he had been staring at her, she grinned at him. "Were you watching me again? Creep." She chuckled.

"Come on, Lana. You know you want me. You admitted it. What do I have to do?"

She sat up on the couch. "Nothing. You're going to do nothing because nothing is going to happen." She grabbed a magazine off the coffee table and started fanning herself with it. 

Jack thought back to one of their conversations from several weeks ago. He hadn't been sure if Lana was flirting with him or if it was all in his head (or just wishful thinking), so one night, on the computer, he decided to bring it up. Lana didn't even try to deny it; two of the things he admired most about her were her confidence in her sexuality and her brutal honesty. She admitted to being attracted to him and to sensing some chemistry between them, but also made it perfectly clear that she wasn't willing to jeopardize her relationship with Ryan for him. As she had put it, her love for Ryan and her own carnal desires didn't always line up exactly, but Ryan was more important than her "sexual wanderlust", as she had called it. 

Jack readjusted his body in his corner of the couch and sighed. "Oh well, it doesn't really matter. Ryan will probably be back soon enough, anyway."

"With the rush hour traffic? It'll take him longer than his estimated thirty minutes."

Jack arched one eyebrow. "Oh? I see you've been giving this some thought."

He'd caught her – he saw it for a split second on her face. "All right, you got me," she said, with the slightest hint of a mischievous grin. 

He felt his cock twitch again with hope. "So what now?"

She gave him a wide-eyed look, incredulous. "Nothing! How many times do I have to say it?"

"It's not like you haven't cheated on him before."

"Hey. That was once, he knows about it, and it was with a girl. It doesn't count."

"It's the same basic principle."

Lana couldn't really argue with his logic. She looked down, silently thinking. Jack watched her, praying this would be the opportunity he'd been dreaming about. 

After what seemed like hours, she looked up at him. "Okay, here's the deal."

"Yes?" Jack hoped she didn't notice the slight quiver in his voice.

Lana looked him squarely in the eye. "No touching."

"No touching?" he repeated, slightly disappointed.

"No touching. But don't worry, I put on a good show. And I hope you do the same. " She gave him another one of her famous sly smiles and leaned forward. "Here's the boundary," she said, indicating one of the spaces between the couch cushions. "I'm serious. To you, this line is the fucking Berlin Wall. Cross it and it's all over."

Jack smirked a bit. "What if you can't keep your hands off of me?"

"I'll try my absolute hardest to control myself," she said sarcastically. "Are we clear on the rules?"

"Absolutely." 

"Good. Take off your shirt."

Jack nodded and pulled the t-shirt, damp with sweat, off over his head and tossed it to the side. "Your turn."

Lana grinned at him and turned so her entire upper body was facing him. She reached up to undo the top button of her shirt and continued down, almost painfully slowly, never taking her eyes off him. Pausing just for a moment, she flung open the shirt and shrugged it off her shoulders in one fluid motion. 

Jack felt his cock begin to strain against the confines of his shorts as he feasted his eyes on the amazing sight before him. The black satin bra could barely contain her magnificent breasts. Smooth, pale flesh spilled out over the tops and sides of the cups and he could see the outline of her nipples poking through the fabric. Barely realizing what he was doing, he moved his hand over the fly of his pants and began gently stroking himself through his shorts.

Lana saw this and shook her head at him. "Pants off." He obeyed the order, undid the button and carefully pulled down the zipper, and slid his shorts down off his narrow hips. His dick, well on its way to its full size, was well defined in his boxer-briefs. He pulled the shorts off from around his ankles and dropped them on the floor as he nodded in her direction. 

Lana took her cue and undid the button of her own shorts. They joined Jack's shorts on the floor and she sat back and opened her legs, exposing her black, slightly damp, satin thong. 

"I believe you're still wearing more than I am," Jack said, breaking the silence. 

"Impatient, are we?" she laughed. Reaching behind her, she undid the back clasp of her bra and released her massive breasts.

Jack groaned again. "If I cross over to the other side of the Berlin Wall, you'll really shoot me down?"

"So fast, you won't know what hit you."

"Damn."

Lana giggled a bit as she slid down on the couch. "Besides, some days I like to keep them all to myself." Without taking her eyes off Jack, she lifted one heavy breast to her mouth and flicked her tongue around her own rosy nipple. 

Jack reached inside his underwear and wrapped his hand around his growing cock. "God, Lana, you're killing me." Her nipple was now in her teeth and she was pulling on it gently, but she had the same pseudo-innocent look on her face. "Can I take off my underwear?"

She smiled. "You're so good to ask. Of course you can." He wasted no time in getting his underwear into the pile of clothing on the floor. Upon noticing his cock, now nearly to its full size, Lana's eyes grew wide. 

Jack noticed this and decided to have some fun. "So, Lana, is it bigger or smaller than Ryan's?"

She dropped her breast and leaned her head back. "I'm not answering."

"One could argue that you already have."

"I'm not listening to you!" she sang. Hooking her thumbs into the strings of her thong, she pushed it off her rounded hips, revealing her neatly-trimmed pussy. Grinning at Jack, she slid down even more on the couch and rested one leg on top of the couch and the other on the coffee table. 

Jack groaned as he tightly gripped his hard cock and began to stroke it. Lana watched a tiny drop of precum appear as she lowered her hand to her opening. She slid in her middle finger and shuddered a bit. "Mmm, Jack, I am so fucking wet right now, you wouldn't believe it." She lifted her hand back up to her mouth and gently licked her juices off her finger. 

The sight was almost too much for Jack as he continued to move his hand up and down. "I want to fuck you so bad, Lana, harder than you've ever been fucked in your life." Lana moaned as she slid two fingers into her pussy and started thrusting against her hand. "You'll really stop this whole thing if I come over there and just slam you into the couch?"

"I said no touching and I meant it," she said, breathing heavily. Her eyes were half-closed and her head was back against the pillow as she brought her other hand down to play with her clitoris. "Shit, Jack, you make me so fucking hot. I do want you, and badly. But knowing I can't have you almost makes it better."

"You can have me. You know that."

She opened her eyes all the way and looked at him, shaking her head. "No. I can't." She started rubbing circles around her clit, increasing the speed and pressure. "But I like having you watch me," she breathed. 

Jack used his precum to lubricate himself and watched her. Lana looked more amazing than she had in any of his fantasies, her huge breasts jiggling and spilling off the sides of her body as she frantically fucked herself. He started to match her increased speed as he pretended his hand was her tight little hole. "Have you ever thought about me while fucking Ryan?" he asked. 

"Mmm..." She was trying to focus only on her growing pleasure and Jack could tell that she was nearing her orgasm. She arched her back and began thrusting even harder, her breasts bouncing all over the place. 

"Say it, Lana," he growled, feeling the tightening in his balls that meant he, too, was getting close. "Say it or I swear I will come over there and keep you from finishing yourself off."

"Yes, you fucking bastard!" She felt the familiar tingling sensation beginning deep in her pussy and drove her fingers as far in as they would go. "Yes, I think about you, yes, I sometimes pretend it's you fucking me, yes, I think about cumming all over you instead of Ryan, yes, I....oh, God!" Her voice trailed off as the orgasm finally exploded all over her body. Jack watched her contort with pleasure on the couch and the look of sheer bliss on her face was enough to drive him over the edge. He moaned her name as he shot ropes of hot white cum onto her half of the couch, not caring where it landed. He collapsed backwards, cock still in hand, and closed his eyes, exhausted. 

They lay in silence for a few minutes, neither of them wanting to ruin the moment. Finally, Lana opened her eyes. "We'd better get all cleaned up before Ryan gets back," she said, looking pointedly at a few drops of cum that had made their way to her stomach and hips. 

"That would probably be a good idea."

"What are you going to do about the couch?"

"Give it a really quick cleaning and then spill a glass of water on it to make it look like I accidentally spilled a glass of water on it."

"Clever," Lana laughed. She stood in front of one of the fans for a few moments. "Well, we picked a good day to do this, we were already sweating to death before Ryan left," she said as she gathered up her clothing. 

"I hear the heat wave's supposed to continue well into next week. Think of the possibilities."

"Asshole." Lana laughed again as she picked up Jack's shorts and threw them at him. "I'll be in the bathroom. With the door locked."

Jack chuckled to himself as he heard her slam the door and click the lock shut. Shaking his head at the thought of what had just happened, he stood up and got dressed. 

Fidelity Test to Pregnancy Test



Megan, my buddy Mike's wife, told me that Sarah had been having fantasies about Mike's cock. You see Mike is rather well endowed, perhaps twice as big as me. Sarah had never been with another man and I think she always regretted that fact. Sarah and I were trying to have a baby, but I had this nagging suspicion that she wasn't completely ready to commit to me until death do we part. In a fit of stupidity I asked my friend to 'test' Sarah's fidelity with Megan's permission. Megan was a little annoyed that Sarah had been fantasizing about her husband and was more than willing to play. 

So the plan was set. We came over for dinner one night and Megan and I made up an excuse to pick up something from the grocery store leaving Mike and Sarah alone so that he could 'test' her. We didn't realize how far Mike would take the test.

Sarah was standing against the counter when Mike came up behind her and put his hands on her shoulders. She was cutting tomatoes and Mike whispered, "You look amazing tonight!" Sarah laughed and returned the compliment. Sarah was wearing a short red dress without panties, something she did frequently when she was feeling naughty. It ALWAYS turns me on when she whispers, "I'm not wearing panties..."

Slightly uncomfortable, but flattered she continued to slice pressed his crotch against her bottom. Sarah turned uncomfortably and tried to escape saying, "Come on, cut it out!"

Mike whispered, "Meagan told me you had a dream about me and about how you have a think for big cocks. Can you feel my penis pressing against you?"

Sarah could feel his penis getting bigger as he pressed it against her. She knew how big he was and she HAD fantasized about holding his cock in her hands, even putting it in her mouth and sucking on it. She regretted telling Meagan about her fantasy. Torn, she knew she should want to escape from his grasp, but she was also curious. Protesting again, Sarah said, "Mike please stop." Sarah put down the knife and put each of her hands on the counter to try to push away. When she did, instead of escaping she merely pressed her ass harder against his engorged penis. Sarah arched her back as she felt the full length of him against her. 

Mike leaned forward against Sarah causing her to exhale loudly, pushing her over the counter as he unzipped his pants and freed his massive cock. Fully erect, Mike is almost ten inches long and no one has ever accused him of being a pencil dick. Mike whispered, "Do you want to feel it again?"

Without thinking Sarah softly mumbled, "yes..."

When he pulled Sarah back up she realized Mike's cock was between her legs, she was straddling his cock. Sarah was already wet from feeling Mike's cock against her ass, now her pussy was in direct contact with his massive shaft. Mike hadn't realized Sarah wasn't wearing panties until her pussy was in direct contact with his cock. 

Thinking Mike was going to penetrate her she said, "I can't, please stop."

Mike responded, "Don't worry, nothing is going to happen, I'm not going to fuck you. I thought you wanted to know what a real cock felt like?" Mike started rubbing his cock back and forth slowly with Sarah providing the lubricant. 

Sarah gasped as her pussy ran up and down his cock. He was so big each stroke lasted forever. She wanted to feel him inside of her, but she convinced herself if it went no further everything would be alright, "Promise me this is it, that you won't go any further."

Mike promised and began picking up the pace, as he did Sarah began to feel herself getting closer and closer to having an orgasm. Spreading her legs and leaning forward Mike kept up the pace rubbing the full length of his penis against her. Sarah finally achieved orgasm and partially collapsed on the countertop exposing her vagina head on to Mike's cock. Mike pressed the tip of his cock against her vagina. Sarah gasped when she felt him against her and secretly wanted him to penetrate her right then. She closed her eyes tightly, spread her legs slightly and pressed back against the tip of his penis. She steadied herself for what she imagined it would feel like to have his massive cock inside of her. Oh, did she want him inside of her she thought to herself. Instead Mike asked, "I know you made me promise, but I know you want to know what it feels like inside of you."

Frustrated, Sarah had wished he had just done it, instead of asking for permission. She had to say no, didn't she? Before she changed her mind she said, "No, we have to stop..." As she said the word stop she felt his penis spasm. Laughing she said, "I guess you were having a good time too." And then she felt it, the tip of his penis was pressed against her vagina and he semen shot inside of her. With the first spasm and her reaction the tip of his penis slid just a little further inside of her. The second pulse was even bigger than the first, filling her womb with his hot semen causing her to scream, "FUCK! You are cuming inside of me! OH GOD, YOU HAVE TO STOP!" 

Mike was surprised and stepped back and finished ejaculating on the floor. Sarah grabbed a paper towel and began rubbing the semen off of her vagina. She then ran to the bathroom and used a wash cloth to clean as much of his semen out of her as possible.

By the time Sarah came out of the bathroom Meagan and I were back from the store. Sarah was obviously upset, but we sat down for dinner anyway. Mike had given me the heads up that Sarah had passed the test, she didn't let him fuck her. He didn't share with me ANY of the details of his attempted seduction and I was pleased that Sarah was uncomfortable as it meant she had been faithful. Little did I know the truth.

During dinner Sarah could feel Mike's semen leaking out of her. Not wanting it soil her dress she kept wiping herself off with her fingers throughout dinner. After desert Sarah feigned a headache and we headed home. Mike gave Sarah a hug and whispered, "Sorry." Sarah didn't respond.

Sarah and I didn't have sex for three weeks. Sarah had a feeling Mike's semen had found their mark. She felt the stream of semen fill her and she just knew. Finally the test confirmed it. Ironically, Sarah and I had been trying to have kids for several months. Part of the reason I asked Mike to 'test' her fidelity was due in part to my own insecurity, but mainly because I was about to have children with her and I wanted to make sure I wasn't fooling myself. 

Sarah called Mike and arranged to stop by his office just after lunch. Mike had no idea why she was coming over, but he was intrigued. Without realizing it, Sarah put on her sexiest underwear, bra and a stunning black suit and skirt. She turned more than a few heads when she walked through Mike's offices. Upon greeting her with a hug, Mike felt himself becoming aroused. He led her to his office and closed the door behind him.

Sarah seemed nervous as she leaned against his desk. Mike completely misread the situation and turned Sarah around against his desk as he had done three weeks earlier in the kitchen. Sarah didn't stop him as he pressed his crotch against her again and whispered, "I see you came back for more." 

Sarah laughed, "Not exactly" as she felt him pressing against her. She didn't move to stop him.

Mike, still clueless, misunderstood again and thinking she wanted him to fuck her pushed her over the desk and lifted her skirt to find her panties. Sarah laid face down on the desk and surrendered to him. Mike pulled her panties down around her ankles, causing Sarah to step out of them as he unzipped his pants freeing his cock.

Mike rubbed the tip of his cock around in her vagina until she was wet enough to lubricate his penis allowing him to penetrate her. As the head of his cock penetrated her, she felt herself stretch farther than she thought possible. Sarah had read that a vagina can expand up-to 200% its normal size if properly aroused and lubricated. She was certain she was 200%+ right now. 

Once she was able to relax, her vagina completely stretched, she began to realize that Mike was going twice as deep as I had been able to reach. It really was an entirely different experience, amazing she thought. Pressed helplessly against the desk she was completely in the moment, experiencing what a large penis was like. Suddenly Sarah told Mike to stop, she said it in a stern enough way Mike immediately pulled out. 

Standing behind her he watched as she stood up and turned around and said, "I want to watch." Sitting back down on the desk she unbuttoned her suit coat and unclasping her bra, freeing her breasts. Mike didn't hesitate as he lifted Sarah's legs and pressed his penis in her vagina again. With one hand he held her waist and the other he used to grasp her breast. He was going full steam as Sarah leaned on her elbows intently watching him penetrate her. Sarah watched as every inch of his massive cock slid inside of her.

Before long Mike said, "I am about to cum, do I need to pull out?" 

Sarah laughed as she collapsed back on the desk and said, "You don't need to worry about that anymore." Sarah felt Mike's semen fill her with each pulse. Sarah relaxed as she felt his hot semen fill her womb once more. Sarah couldn't believe how full she felt with his cock and his semen inside of her. Each time she thought he was spent she felt more semen fill her. 

Almost done, Mike almost out of breath said, "I thought you weren't able to use birth control..." and shot his last load inside of Sarah, collapsing next to her on the desk, turning to lay on his back. 

Sarah laid on her side and reached over and grasped Mike's soft, but still large penis. She marveled how it dwarfed her hand, being almost twice the size of my average to small sized cock. She then asked, "Have you and Meagan thought about having kids?" 

Mike, bothered by the question, answered, "We have talked about it, but she wants to focus on her career at the moment, maybe in a couple years we will talk about it. You guys were talking about having kids, right?" 

Sarah sat up and straddled Mike, resting her vagina on his hardening cock. She smiled as she took off her suit coat and bra, fully exposing her chest and asked, "Do you love Megan?" After she asked the question she began grinding back and forth over his partially erect cock.

Mike stuttered as Sarah smiled at him. Leaning down she kissed his lips, his penis lifting its head as if to enter her automatically. Mike grasped her waist and thrust his penis inside of her again. Sitting up on his cock, Sarah said, "...and yes to both of your questions."

Mike, not recalling what she was saying yes to said, "Huh?'

Sarah explained, "Yes, I am not able to use birth control and yes we were trying to have kids." 

Mike finally realized the gravity of what she said stuttering, "We... just... Oh God."

Sarah smiled and almost laughed saying, "Don't worry, you didn't get me pregnant today, that happened three weeks ago when you ejaculated inside of me at dinner." 

Mike's cock started to shrink as he remembered their first encounter.

Sarah, leaned back and reached around behind her and began massaging Mike's balls saying, "Don't go limp on me now big boy." She started riding him again, finally enjoying being in control of the situation for the first time. She wanted his cock inside of her and she wanted him, at least right now. Sarah managed to have several more orgasms before Mike came again. Sarah got dressed and walked to the door and said, "Call me tonight." And walked out.

Mike sat in his office completely wrecked. He said to himself, over and over, "She's pregnant?"
